The idea that with raid utility should come low dps is very disturbing to me.

I've been maining RPR since EW release, and before that I was a BLM main. I want to voice a few concerns here. RPR feels good, plays good, and fits a role of between utility and greedy DPS, but I would argue more on the side of being greedy and I'll lay out my reasons in a bit.

I do think RPR needs some slight tuning.
It's true that when I compare my DPS to others, I to tend to be in the top if not first, but there are a few factors you have to take into account.
1. I'm an experienced raider and active in the min/max community (the balance)
2. I have 575 melded gear or better
3. Most players don't use their class to the extent they can be used
Even when I'm out DPSing, it's hard to gauge if it's actually just too strong or if there's more to it than that.
I out DPS'd by 2k more than once, but sometimes those were other reapers.
I've been out DPS'd by other reapers
I've been out DPS'd by monks and sams, even RDM.
But these were situational

During an EX, I was pushing out good timings and not missing my burst windows, but was getting out DPS'd by a monk and SAM.
But overall, I will say that I've been top DPS, thus why we may need a bit of tuning... But not these massive nerfs some people are calling for...

Arcane crest is a 10% damage reduction for self for 5 seconds, if broken (exceeds 10% damage) it releases a 100 potency heal over 15 seconds to nearby members.
First, I have to say that the usefulness of this is limited. There's no way you are replacing a normal aoe heal with this for a raid wide. It does work pretty good with shield heals, but all this does is give everyone a safety net. I would like to see these stats that were mentioned however, perhaps I'll change my mind, but I fear there's more to those numbers than people are actually saying given the drastic calls for extreme nerfs.

Arcane circle is a greedy utility. I know, I know. We do give 3% damage buff to everyone... But that's not why we use it, not primarily. Arcane circle will give us stacks of immortal sacrifice based on other members doing attack abilities, which empowers our Plentiful Harvest. PF is used in our burst windows. We only use Arcane circle for our own DPS gains, it just so happens to align well with the 2 minute raid window. I suppose you could remove the 3% damage buff to everyone, honestly we wouldn't feel a huge impact on this, because we don't use this under the intention of helping the raid.
